Rulers on the road: Itinerant rule in the Holy Roman Empire, AD 919–1519

American Journal of Political Science, EarlyView.
Abstract Itinerant rule, rule exercised through traveling, was a common yet insufficiently researched, premodern form of governance. Studying the determinants of ruler itineraries in the Holy Roman Empire, AD 919–1519, we argue that rulers' visits targeted “marginal” elites.

The former distribution of White‐tailed Eagles in Iberia, the Mediterranean and the Middle East: a case study of the importance of understanding historical distribution in informing current conservation and restoration interventions

Ibis, EarlyView.
The importance of considering historical data in developing conservation and restoration measures for individual species and for wider ecological restoration has been pointed out by recent reviews but often remains neglected in practice. This paper provides a case study illustrating the issue through a review of the former breeding distribution of the ...

Modeling of the geographical distribution of two forest‐forming fucoids in the Strait–Alboran demarcation (southern Iberian Peninsula): Implications for conservation and restoration

Journal of Phycology, EarlyView.
Abstract Marine forests formed by canopy‐forming brown algae of the former Cystoseira complex are key habitat‐forming components of Mediterranean coastal ecosystems, supporting biodiversity and multiple ecosystem functions. However, many populations have declined in recent decades due to increasing anthropogenic pressures and climate change, raising ...

Toward Consistent Canopy Characterization From Low‐Cost UAV Imagery

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We show that UAV‐based crown segmentation can reliably characterize dominant canopy trees in a structurally complex tropical forest. Focusing on these key individuals improves the assessment of forest structure and supports ecological monitoring at multiple scales. ABSTRACT Monitoring tropical forest structure at landscape scale requires cost‐effective

Eyespots in Automeris Moths Mimic Sympatric Owl Species (Lepidoptera: Saturniidae)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Eyespot mimicry is a common anti‐predator strategy in moths, yet the mechanism underlying its effectiveness in Automeris remains unresolved. Using species distribution models, convolutional neural networks, and saliency mapping, we show that Automeris eyespots are visually confusable with sympatric owl eyes and that this similarity is concentrated in ...

Real Time Airborne Monitoring for Disaster and Traffic Applications [PDF]

, 2011
Remote sensing applications like disaster or mass event monitoring need the acquired data and extracted information within a very short time span. Airborne sensors can acquire the data quickly and on-board processing combined with data downlink is the ...

Morphodynamic adjustment in a watershed affected by megafires: Deadman River, British Columbia, Canada

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The Deadman River watershed (British Columbia, Canada) was severely impacted by the Sparks Lake Fire in 2021. Timelapse photogrammetry reveals sharp post‐fire channel widening and increase in migration rate. Through multispectral remote‐sensing analysis, these morphodynamic changes are related to burn severity affecting the watershed.
